I think, i imagine....
Well, like TM or FPS or other games, i think they will insert fixed maps (we can say 80, for example) and the others created by players with editor. If the style is this, sure the players will share maps.
Now, if we share maps, we can create quests, scripting in the editor (basic) and with ManiaScripts for the skilled coder (advanced).
Than we easily have map as a quest.
Introducing time in quest is not a good idea, or the free roaming go bad.
Well, i expected, more than Questmania, a MafiaMania ahuahua, where players can do jobs for other players, the rich is powerful, the noob must sell drugs, someone kill the boss and become boss, and so on...
Like i said before if all is connected by a common editor, we can thnk a million things.
Maybe on QM, having LVLs, we can have the possibility to have an editor based on rank.
I have server LVL 20 and i unlocked some monsters, so i can script quest with the lvl 20 difficulty.
As you see is very large.
I like very much the Mmorpg persistent worlds, but to be a great game, never to be forgotten, it need the greatest idea of the century, hmmmm, introducing someting give him the possibility the players get something to resell and create the real commerce.
Coppers (or the future name will have Nadeo virtual money) are crucial this time, not like now.
Hylis, this time the Copper must have its route:
X - Y you want this? Pay coppers.
Y - I wanna sell this, give me copper mate!!
Z - Ok take coppers.
X - Hey Z if you give me this i give you coppers!
X -Y -Z -X -Y -Z -X .........
Imagine for weapons, maps, cars, servers, soldiers, team, etc!!!
Sorry for the long post!
